This mod adds so many Quality of Life modifications, it's really refreshing. Love the fort condor teleport, the early game Enemy Away and the ability to Skip huge portions of dialogue!
It overall edits a lot of things, adds quite a few unexpected bosses, changes items, materias, and equipment fairly drastically, and even grants you a way to easily grind materia levels late game!
But then there are the bosses... they take a long time to kill for virtually no reason in my opinion; an opinion that doesn't seem to be shared by many, yet no one can deny that the outcome of storyline bosses' battles is already determined 1/4th of the way into the battle. It just becomes a process of "Rinse and Repeat until the boss is dead". Of course, there is the possibility that the fight will drag on long enough for you to run out of items, but you get easily used to the bosses' huge HP that you just instinctively gather quite a few items before each boss fight.
Then there are the optional bosses. 100x harder than the storyline bosses. I don't enjoy difficulty and I thought the storyline bosses were well balanced and never really had anything close to a problem with any of them, but the optional bosses in this mod just reminds me so much of 1.3 where you just end up needing a way too specific setup to be able to win the fight. It just destroys any kind of build creativity since you have to abuse absolutely everything you can to beat those bosses.
I really loved the game otherwise, but I am unable to finish it at this point because I don't find Disc 3 fun at all. As I said, I don't like difficulty; especially extreme level of difficulty, so this wasn't for me. Even saying that, Disc 1-2 were really awesome.
As a side note: Death will bring happiness to everyone in the slums. --My wife playing FF7 and renaming Aeris to "Death".
